I need to join 3 x 2m pieces of alu scaff together and suspend a 5kg weight in the centre for about 2 hours and presume the first link would do the trick but can't easily get to London in time to collect.
Thanks. Is one safer than the other i.e. internal Vs external? And is there a max length? Could I do 3 x 2 meter with 2 joining pieces or even 4 X 2 meter with 3 joining pieces?
Where can I buy (not rent) these?

Specifically that rather than something like this:

The latter to me looks less secure.
